1496 COLEOPTERA 



With much pleasure I name this interesting little Cossonid in honour 

 of Mr. A. T. Urquhart. 



2578. A. pedatUS, ''-s. SJiining, yellowish-brown, tarsi and 

 antennas paler, but not rufescent. 



Rather shorter, and distinctly broader, than A. urqukarti. Bos- 

 trum shorter and thicker, more appreciably, yet only slightly, nar- 

 rowed behind, its punctures larger and arranged in longitudinal 

 series. Head less immersed ; the eyes, therefore, more distant from 

 the thorax, they are also less depressed. Thorax shorter, widest 

 before the middle, without frontal constriction, its punctuation 

 rather coarser and closer. Elytra shorter and broader, their 

 greatest wddth near the hind thighs, their punctures coarser and 

 closer. 



Underside as pale as the upper surface, but with the middle of 

 the second ventral segment pitchy-brow^n, it is more or less coarsely 

 punctured, with slender setse ; second segment more distinctly punc- 

 tured than in A. nrquharti, its frontal suture better marked and more 

 curvate ; metasternum and basal segment less depressed. 



Penultimate joint of the tarsi more expanded, and a little emar- 

 ginate at the apex. This is the most important differentiating 

 character. 



Length, 1 J^ lines ; breadth, quite f line. 



Mount Pirongia. Two, amongst leaf-mould brought by Mr. 

 Urquhart. 



2579. A. sternalis, ii-s. Elongate-ovate, convex, shining, rufo- 

 piceous, legs fuscous, tarsi paler, antennte reddish, club infuscate; 

 the clothing like that of the two preceding species. 



Thorax rather longer than it is broad, more narrowed anteriorly 

 than behind, yet not much wider at the middle than it is at the 

 base; distinctly, rather closely, and almost rugosely punctured. 

 Elytra widest near the middle, their series of punctures coarse, with 

 rather narrow intervals, declivity striate. 



Underside fuscous, more or less coarsely (comparatively) punc- 

 tured, with a distinct seta in each puncture. Prosterniim truncate 

 and finely ciliate in front. Metasternum, and two basal abdominal 

 segments, longitudinally depressed ; third and fourth segments with 

 broad deep sutures in the middle only (that is, slender at the sides) ; 

 fifth finely punctured and impressed ; the two basal segments so 

 marked with slight transversal rugosities that the suture between 

 them cannot be accurately defined. 



This species is most nearly allied to A. 'pedatus ; the punctures 

 on the thorax smaller, but not at all fine, in comparison with the 

 small size of the insect, they are also closer; the punctures of the 

 elytra closer to one another, but not so large ; the third tarsal joint 

 similar, but not quite as broad. 



The principal differences exist on the lower surface, the front of 

 the prosternum is the most obvious. 



Length, I^l lines; breadth, f line. 



Mount Pirongia. One, brought by Mr. Urquhart amongst leaves.
